RESUMO

BACKGROUND: Maximizing quality of life (QoL) is a major goal of care for people with dementia in nursing homes (NHs). Social determinants are critical for residents' QoL. However, similar to the United States and other countries, most Canadian NHs routinely monitor and publicly report quality of care, but not resident QoL and its social determinants. Therefore, we lack robust, quantitative studies evaluating the association of multiple intersecting social determinants with NH residents' QoL. The goal of this study is to address this critical knowledge gap. METHODS: We will recruit a random sample of 80 NHs from 5 Canadian provinces (Alberta, British Columbia, Manitoba, Nova Scotia, Ontario). We will stratify facilities by urban/rural location, for-profit/not-for-profit ownership, and size (above/below median number of beds among urban versus rural facilities in each province). In video-based structured interviews with care staff, we will complete QoL assessments for each of ~ 4,320 residents, using the DEMQOL-CH, a validated, feasible tool for this purpose. We will also assess resident's social determinants of QoL, using items from validated Canadian population surveys. Health and quality of care data will come from routinely collected Resident Assessment Instrument - Minimum Data Set 2.0 records. Knowledge users (health system decision makers, Alzheimer Societies, NH managers, care staff, people with dementia and their family/friend caregivers) have been involved in the design of this study, and we will partner with them throughout the study. We will share and discuss study findings with knowledge users in web-based summits with embedded focus groups. This will provide much needed data on knowledge users' interpretations, usefulness and intended use of data on NH residents' QoL and its health and social determinants. DISCUSSION: This large-scale, robust, quantitative study will address a major knowledge gap by assessing QoL and multiple intersecting social determinants of QoL among NH residents with dementia. We will also generate evidence on clusters of intersecting social determinants of QoL. This study will be a prerequisite for future studies to investigate in depth the mechanisms leading to QoL inequities in LTC, longitudinal studies to identify trajectories in QoL, and robust intervention studies aiming to reduce these inequities.

RESUMO

STATEMENT OF PROBLEM: Clinical studies regarding satisfaction and occlusal forces with the complete denture in relation to the menopause are sparse. PURPOSE: The purpose of this clinical study was to compare satisfaction levels and occlusal force with complete dentures in premenopausal and postmenopausal Indian women. MATERIAL AND METHODS: Twenty premenopausal (group pre-MP) and 20 postmenopausal (group post-MP) completely edentulous participants were selected based on inclusion and exclusion criteria, and estradiol levels were measured. Complete dentures were delivered to all participants following standard fabrication and insertion protocols. Three months after denture insertion, when participants were free of postinsertion complaints, satisfaction level (by using a valid and reliable questionnaire), depression level by using the Patient Health Questionnaire, (PHQ-9) and occlusal force (with a gnathodynamometer) were measured. The obtained data of all parameters were tabulated and compared by using a statistical software program (α=.05). RESULTS: For questions pertaining to the overall satisfaction of maxillary and mandibular dentures, the 2 study groups encountered a significant difference with the premenopausal group showing significantly higher satisfaction levels (P<.001). Depression scores in the postmenopausal women group were significantly higher than those of the premenopausal women group (P<.001). A negative correlation was found between the overall satisfaction with complete dentures and depression levels in the participants indicating decreased overall satisfaction with increasing depression levels in participants (rho=-0.698). The premenopausal group recorded significantly higher estradiol levels than the postmenopausal group (P<.001). Mean occlusal force with complete dentures in the premenopausal women group was significantly higher than that of the postmenopausal women group (P<.001). A positive correlation was found between the estradiol levels and occlusal forces in the participants indicating that with decreasing estradiol levels, the occlusal forces decrease in the participants (r=0.740). CONCLUSION: Satisfaction levels and occlusal force with complete dentures were significantly higher in premenopausal women group than in the postmenopausal group.

RESUMO

Patients with serious illnesses such as cancer, advanced organ failure, dementia and COVID-19 rely on medications to alleviate suffering from uncontrolled symptoms. Numerous actual or threatened shortages of key medications used to provide palliation have been reported during the COVID-19 pandemic. This article explores the nature of these shortages, factors that have contributed to them and strategies to mitigate them. It calls on all levels of the healthcare system and the government to address this problem. Shortages in these medications are as serious as shortages in medications used to cure or control diseases.

RESUMO

BACKGROUND: Patients often view "palliative care" (PC) as an approach that is synonymous with end-of-life and death, leading to shock and fear. Differing cultural and social norms and religious affiliations greatly determine perception of PC among diverse populations. METHODS: This prospective observational study aimed to explore perceptions of PC among South Asian community members at one Canadian site. Patients who identified themselves as being of South Asian origin were consented and enrolled at a PC Clinic at a community hospital in Brampton, Ontario serving a large South Asian population. Participants filled out an 18-question survey created for the study and responded to a semi-structured interview consisting of 8 questions that further probed their perceptions of PC. Survey responses and semi-structured interviews content were analyzed by four authors who reached consensus on key exploratory findings. RESULTS: Thirty-four participants of South Asian origin were recruited (61.8% males), and they were distributed by their age group as follows: [(30-49) - 18%; (50-64) - 21%; (65-79) - 41%; (≥ 80) - 21%]. Five main exploratory findings emerged: (i) differing attitudes towards talking about death; (ii) the key role of family in providing care; (iii) a significant lack of prior knowledge of PC; (iv) a common emphasis on the importance of alleviating suffering and pain to maintain comfort; and (v) that cultural values, faith, or spiritual belief do not pose a necessary challenge to acceptance of PC services. CONCLUSIONS: Observations from this study provide a source of reference to understand the key findings and variability in perceptions of palliative care in South Asian communities. Culturally competent interventions based on trends observed in this study could assist Palliative Physicians in delivering personalized care to South Asian populations.

RESUMO

Colon-targeted microparticles loaded with a model anti-inflammatory drug were fabricated using especially designed acrylic acid-butyl methacrylate copolymers. Microparticles were prepared by oil-in-oil solvent evaporation method using Span 80 as emulsifier. Microparticles were found to be spherical in shape, hemocompatible and anionic with zeta potential of -27.4 and -29.0 mV. Entrapment of drug in the microparticles was confirmed by Fourier transform infrared (FTIR) spectroscopy. However, X-ray diffraction (XRD) and differential scanning calorimetry (DSC) revealed amorphous nature of microparticles due to the dilution effect of amorphous polymer. The microparticles released less than 5% drug at pH 1.2, while more than 90% of the drug load was released at pH 7.4. This suggested the colon targeting nature of the formulations. In experimentally developed colitis in Wistar rats, the microparticle formulation showed significant reduction (p < .05) in the disease activity score (disease symptoms), the colon-to-body weight ratio (tissue edema) and the myeloperoxidase, tumor necrosis factor (TNF)-α and interleukin (IL)-1ß activities.

RESUMO

BACKGROUND: Transcranial direct current stimulation (tDCS) is proven to be safe in treating various neurological conditions in children and adolescents. It is also an effective method in the treatment of OCD in adults. AIM: To assess the safety and efficacy of tDCS as an add-on therapy in drug-naive adolescents with OCD. METHODS: We studied drug-naïve adolescents with OCD, using a Children's Yale-Brown obsessive-compulsive scale (CY-BOCS) scale to assess their condition. Both active and sham groups were given fluoxetine, and we applied cathode and anode over the supplementary motor area and deltoid for 20 min in 10 sessions. Reassessment occurred at 2, 6, and 12 wk using CY-BOCS. RESULTS: Eighteen adolescents completed the study (10-active, 8-sham group). CY-BOCS scores from baseline to 12 wk reduced significantly in both groups but change at baseline to 2 wk was significant in the active group only. The mean change at 2 wk was more in the active group (11.8 ± 7.77 vs 5.25 ± 2.22, P = 0.056). Adverse effects between the groups were comparable. CONCLUSION: tDCS is safe and well tolerated for the treatment of OCD in adolescents. However, there is a need for further studies with a larger sample population to confirm the effectiveness of tDCS as early augmentation in OCD in this population.

RESUMO

Background: Lichen planus is a chronic inflammatory disease of the skin and mucous membrane with higher predilection seen in the female population. Oral lichen planus (OLP) has been associated with various etiological factors, such as stress, hormonal imbalance, and immunological variation. The purpose of this study was to assess serum and salivary estrogen (E2) levels in OLP patients and correlate them with stress levels. Objectives: This study aimed to evaluate serum and salivary estrogen levels in female patients with OLP, along with the assessment of stress and its correlation with estrogen levels. Methods: A total of 78 females, 39 clinically diagnosed with OLP and 39 healthy females, were included in the study as the case and control groups, respectively. 2 ml each of salivary and serum samples was obtained from each participant to measure the estrogen levels. Stress levels in the study group patients were assessed using the Depression Anxiety Stress Scale (DASS-21) and the Perceived Stress Scale (PSS). The nonparametric Mann-Whitney test was used for intergroup comparisons. Results: Significantly higher serum estrogen levels with higher DASS-21 and PSS scores were noted in patients with OLP. Overall, significant positive correlations were observed between salivary E2 and serum E2 (r = 0.361, P = 0.001). There was a positive correlation between salivary and serum E2 and DASS score (r = 0.410, P < 0.001, and r = 0.768, P < 0.001, respectively), serum/salivary E2 and PSS score (r = 0.745, P < 0.001, and r = 0.410, P < 0.001, respectively), and DASS score and PSS score (r = 0.878, P < 0.001). Conclusion: Estrogen can be used as a useful biomarker for OLP in the future. Salivary samples can prove to be an accurate and feasible alternative to serum estrogen level determination. We also suggest that OLP patients must be given supportive psychological treatment for improved life quality and disease management.

RESUMO

OBJECTIVES: Long-term care (LTC) homes provide personal and medical care 24/7 to individuals unable to live at home due to illness or disability and are often the final place of care and death for their residents. Therefore, LTC homes are tasked with providing quality end-of-life care, often requiring injectable symptom management medications to relieve distressing symptoms (eg, pain). In this study, we aimed to understand the enablers and barriers to prescribing and administering end-of-life symptom management medications in LTC homes. DESIGN: Qualitative study. SETTING AND PARTICIPANTS: From February 2021 to December 2022, we conducted virtual semi-structured interviews with health care providers (physicians and nurses) who worked in Ontario LTC homes and family caregivers of residents who died in LTC. METHODS: We analyzed interview transcripts using thematic analysis. RESULTS: We identified 4 themes related to factors that may impact the prescribing and administering of medications for end-of-life symptom management: (1) identifying the end-of-life period and symptoms, (2) communication among health care providers and between health care providers and family caregivers, (3) health care provider competency with end-of-life medications, and (4) resources for LTC staff to support medication prescribing and administrating. CONCLUSIONS AND IMPLICATIONS: In LTC, there are distinct challenges in the prescribing and administrating of end-of-life symptom management medications. Our findings can be used to inform interventions aimed at improving end-of-life care for LTC residents. However, these interventions require buy-in and investment from the provincial government and the LTC sector.

RESUMO

Background: At the end of life, individuals may experience physical symptoms such as pain, and guidelines recommend medications to manage these symptoms. Yet, little is known about the symptom management long-term care (LTC) residents receive at the end of life. Our research team developed a metric-whether residents receive one or more prescriptions for an end-of-life symptom management medication in their last two weeks-to explore end-of-life care for LTC residents. This qualitative study aimed to inform the refinement of the end-of-life prescribing metric, including the acceptability and applicability to assess the quality of a resident's symptom management at end-of-life. Methods: We conducted 14 semi-structured interviews with Ontario health-care providers (physicians and nurses) who work in LTC homes and family caregivers of residents who died in LTC. Interviews were conducted virtually between February 2021 and December 2022, and were analyzed using thematic analysis. Results: We identified three major themes relating to perceptions of the metric: 1) appropriateness, 2) health-care provider applicability, and 3) caregiver applicability. Participants noted that the metric may be appropriate to assess end-of-life care, but noted important nuances. Regarding applicability, health-care providers found value in the metric and that it could inform their practice. Conversely, caregivers found limited value in the metric. Conclusion: The proposed metric captures a very specific aspect of end-of-life care-whether end-of-life medications were prescribed or not. Participants deemed that the metric may reflect whether LTC homes have processes to manage a resident's end-of-life symptoms with medication. However, participants thought the metric could not provide a complete picture of end-of-life care and its quality.

RESUMO

BACKGROUND: Methadone take-home doses for opioid dependence treatment are strictly regulated due to diversion and overdose concerns, so patients must visit the clinic daily for dispensing. This was also done in India until the COVID-19 pandemic, when lockdown restriction compelled take- home dispensing of methadone. This study examined experience of patients who received take- home methadone during COVID-19 pandemic in India. METHODS: Observational, cross-sectional design. We contacted all consenting methadone centres in India during the lockdown and selected those that provided take-home doses for the study. Patients who received daily methadone before the lockdown and take-home doses after were interviewed using a study-specific questionnaire. RESULTS: The study had 210 participants. Take-home methadone was dispensed for 2.5 days on average in each dispensing. When taking methadone at home, 3.3% split their dose 25% took less than the prescribed dose to save it for a rainy days, and 3.3% reported an overdose episode. Adherence improved in 58.6% participants after take-home methadone. Participants perceived many benefits from take-home methadone such as reduced hospital visits and travel time to collect methadone, improvement in work, and financial savings. About 54.3% participants reported storing their take-home doses safely, and 1.9% reported that their family consumed methadone by mistake. CONCLUSIONS: Take-home methadone was found to be beneficial to most participants in terms of time saved and improved productivity. Preconceived concerns of providing take-home methadone in terms of its overdose, diversion, or accidental ingestion by others are not commonly seen when individuals are provided take-home doses of methadone.

RESUMO

BACKGROUND: Medications are often needed to manage distressing end-of-life symptoms (eg, pain, agitation). OBJECTIVES: In this study, we describe the variation in prescribing rates of symptom relief medications at the end of life among long-term care (LTC) decedents. We evaluate the extent these medications are prescribed in LTC homes and whether prescribing rates of end-of-life symptom management can be used as an indicator of quality end-of-life care. DESIGN: Retrospective cohort study using administrative health data. SETTING AND PARTICIPANTS: LTC decedents in all 626 publicly funded LTC homes in Ontario, Canada, between January 1, 2017, and March 17, 2020. METHODS: For each LTC home, we measured the percent of decedents who received 1+ prescription(s) for a subcutaneous end-of-life symptom management medication ("end-of-life medication") in their last 14 days of life. We then ranked LTC homes into quintiles based on prescribing rates. RESULTS: We identified 55,916 LTC residents who died in LTC. On average, two-thirds of decedents (64.7%) in LTC homes were prescribed at least 1 subcutaneous end-of-life medication in the last 2 weeks of life. Opioids were the most common prescribed medication (overall average prescribing rate of 62.7%). LTC homes in the lowest prescribing quintile had a mean of 37.3% of decedents prescribed an end-of-life medication, and the highest quintile mean was 82.5%. In addition, across these quintiles, the lowest prescribing quintile had a high average (30.3%) of LTC residents transferred out of LTC in the 14 days compared with the highest prescribing quintile (12.7%). CONCLUSIONS AND IMPLICATIONS: Across Ontario's LTC homes, there are large differences in prescribing rates for subcutaneous end-of-life symptom relief medications. Although future work may elucidate why the variability exists, this study provides evidence that administrative data can provide valuable insight into the systemic delivery of end-of-life care.

RESUMO

OBJECTIVE: To examine changes in the prescribing of end-of-life symptom management medications in long-term care (LTC) homes during the COVID-19 pandemic. DESIGN: Retrospective cohort study using routinely collected health administrative data in Ontario, Canada. SETTING AND PARTICIPANTS: We included all individuals who died in LTC homes between January 1, 2017, and March 31, 2021. We separated the study into 2 periods: before COVID-19 (January 1, 2017, to March 17, 2020) and during COVID-19 (March 18, 2020, to March 31, 2021). METHODS: For each LTC home, we measured the percentage of residents who died before and during COVID-19 who had a subcutaneous symptom management medication prescription in their last 14 days of life. We grouped LTC homes into quintiles based on their mean prescribing rates before COVID-19, and examined changes in prescribing during COVID-19 and COVID-19 outcomes across quintiles. RESULTS: We captured 75,438 LTC residents who died in Ontario's 626 LTC homes during the entire study period, with 19,522 (25.9%) dying during COVID-19. The mean prescribing rate during COVID-19 ranged from 46.9% to 79.4% between the lowest and highest prescribing quintiles. During COVID-19, the mean prescribing rate in the lowest prescribing quintile increased by 9.6% compared to before COVID-19. Compared to LTC homes in the highest prescribing quintile, homes in the lowest prescribing quintile experienced the highest proportion of COVID-19 outbreaks (73.4% vs 50.0%), the largest mean outbreak intensity (0.27 vs 0.09 cases/bed), the highest mean total days with a COVID-19 outbreak (72.7 vs 24.2 days), and the greatest proportion of decedents who were transferred and died outside of LTC (22.1% vs 8.6%). CONCLUSIONS AND IMPLICATIONS: LTC homes in Ontario had wide variations in the prescribing rates of end-of-life symptom management medications before and during COVID-19. Homes in the lower prescribing quintiles had more COVID-19 cases per bed and days spent in an outbreak.

RESUMO

The purpose of palliative care is to ease the suffering of individuals with a serious and often life-limiting illness throughout the course of their disease by providing holistic care that considers the physical, spiritual, and psychosocial dimensions of health and well-being. Research shows that a palliative approach to care is cost-effective for the healthcare system and results in improved quality of life for patients and their loved ones. However, it is well-documented in the literature that structurally vulnerable populations have greater difficulty accessing equitable and culturally safe palliative care. Several domains are identified as contributing factors to the disparities seen in the literature, including systemic racism, cultural differences around death and suffering, and language barriers. Although Canada has had a national palliative care framework since 2018, ongoing issues of access and equity continue to disproportionately impact certain groups, including racially marginalized, immigrant, and low-income communities. In this commentary, successes and ongoing gaps in providing culturally safe and anti-racist palliative care are explored. In these proposed interventions, we advocate for a palliative approach to care that is grounded in equity, justice, and human rights.

RESUMO

OBJECTIVE: The aim is to assess the sensory processing difficulties in children and adolescents with ADHD. METHODS: In all, 38 ADHD children of the age group 6-14 years and 34 age- and gender-matched typically developing controls were included in the study. Sensory processing was assessed on Child Sensory Profile-2. The child behavior checklist and Weiss functional impairment rating scale were applied to assess behavioral problems and functional impairments, respectively. RESULTS: A significantly higher sensory processing difficulties were seen in children with ADHD than typically developing controls. There were positive correlations between the scores of Child sensory profile 2 with internalizing (with Sensitivity p = .036, Avoiding p = .001, and Auditory p = .029) and externalizing T scores (with Seeking p = .031, Movement p = .025, and Visual p = .018) of CBCL and also with scores of Weiss functional impairment rating scale (with Seeking p = .001, Sensitivity p = .019, and Registration p = .045). CONCLUSIONS: Sensory problems were common in children with ADHD and add to the functional impairments.

RESUMO

Pediatric Bipolar Disorder (BD) is a serious mental illness that affects children and adolescents, characterized by episodes of mania, depression, and mixed episodes. Recent studies have suggested that abnormalities in the white matter (WM) may be a contributing factor. The neuropathogenesis of BD in children is not well-described, and research in this area is limited. Euthymic phase is a period in which clinical symptoms are present but not severe enough to significantly impact mood and daily behavior. In order to better understand the WM changes associated with BD in children, this study utilized Diffusion Tensor Imaging (DTI), to investigate alterations in WM microstructure. 20 confirmed euthymic BD children (aged 7-16) and 20 typically developing children were included in the study. DTI scans were obtained using a 3 T Magnetom Skyra and were analyzed using tract-based spatial statistics (TBSS) to examine changes in fractional anisotropy (FA), axial diffusivity (AD), radial diffusivity (RD), and mean diffusivity (MD). Results showed that compared to the healthy control group, the euthymic BD group exhibited increased FA, AD, RD, and MD values in several brain regions, including the thalamus, precentral corticospinal tract, and superior longitudinal fasciculus. Conversely, decreased values were observed in the body of the corpus callosum and inferior fronto-occipital fasciculus. These findings suggest that alterations in WM microstructure are a hallmark of pediatric bipolar disorder. These findings provide important insights into the brain changes associated with pediatric bipolar disorder and open the door for new avenues of research.

RESUMO

Aim: The study investigate the severity of perceived stress and wide domains of psychiatric symptoms reported on initial screening in hospitalized patients of COVID-19 with a second aim to determine the role of sociodemographic factors and coping styles in the hospitalized patients of COVID-19. Method: Total 224 patients of COVID-19 infection, hospitalized in various isolation facilities were assessed via web-based self-reported questionnaires on perceived stress scale, brief cope inventory, and DSM-5 crosscutting level-1 questionnaire. Results: Majority of the patients reported moderate level of stress followed by mild and severe. Depression and Anxiety symptoms were most common psychopathologies though the patients have reported greater severity in various domains of psychiatric symptoms. Coping styles explains most of variance (64.8%) of the perceived stress. Similarly total PSS scores, coping styles, COVID-19 status and sociodemographic factors contributed significantly to the variance of all psychiatric symptoms. Conclusion: Factors like female gender, being married, belonging to nuclear families, service class and urban domicile are the significant factors determining higher risk of stress and developing more psychopathologies. Furthermore, coping styles used by the patients have a greater moderating effect on mental health symptoms and their perceived stress which can be a major area for interventions to reduce the mental health morbidities.

RESUMO

Response inhibition is one of the crucial cognitive domains that exhibit deficit in children with ADHD. To further elucidate it, this study examines the task-based functional-connectivity in children with attention deficit hyperactive disorder (ADHD). We acquired the fMRI data of 16 unmedicated children with ADHD and 16 typically developing (TD) children who performed the flanker task. MVPA and seed-based connectivity analysis was performed to identify the abnormal connectivity pattern across the whole brain. MVPA revealed that six important regions, namely the right IFG, right SMA, bilateral precentral gyrus, left DLPFC, and left cerebellum, had abnormal connectivity in children with ADHD while they performed the cognitive control task. Out of these six regions, four were further used for whole-brain seed-based functional connectivity analyses, which revealed patterns of significantly altered connectivity across multiple regions. Signal intensities changes were also extracted to perform BOLD- reaction time (RT) correlation analysis, that suggest positive correlation between left DLPFC and right IFG. Overall, the results suggest that children with ADHD are unable to endure high cognitive control demand. Our findings highlight the utility of analyzing brain connectivity data in identifying the abnormal connectivity in children with ADHD.
